Late symptoms

Candace
My name is candace, I am we years old and I start my period on the 28 of every month for the past 6 months. Today is 3/8/2016 I don't have symptoms besides sore boobs expecially when I wake up, they are full and swollen, my uterus feels full like I'm going to get my period I'm gaining belly weight I'm hot in the mornings. I'm not sure what's happening any thoughts? I was pregnant years ago had an ectopic pregnancy and didn't know I was pregnant till I had horrible cramping and I have a big dark line going down my belly button. I was 14 weeks before I found out.
